Under such severe working conditions, the core rod is scrapped in failure modes such as nose collapse, steel sticking, cracking and the like, the service life of the core rod is shortened, and the replacement frequency is very high, so that the production efficiency and quality of the steel pipe are affected, and the production and product quality of the large-scale seamless steel pipe are both greatly affected.
In actual production, a plurality of core rods are recycled on a steel rolling platform, and the reciprocating circulation actions comprising hot rolling of steel pipes, conveying and cooling, conveying and translating and hot rolling of the steel pipes are sequentially executed by the plurality of core rods, however, the existing core rod conveying equipment, particularly the conveying and translating equipment, is mainly in a lifting hook structure, namely, the cooled core rods are horizontally lifted and are placed at the core rod feeding end of the hot rolling steel pipe part again, and the following three problems exist in the process:
1. the efficiency of lifting the core rod by the lifting hook is lower, and the core rod has a certain length, so that the core rod discharge end is connected with the core rod feed end, and only one core rod can be lifted and conveyed at the same time, thereby lowering the conveying and translation working efficiency of the core rod;
2. the energy consumption of the lifting core rod is too high, a great amount of electric energy is consumed in the lifting process of the lifting core rod by the lifting hook, and the lifting kinetic energy of the lifting core rod generated by the lifting process is unnecessary, because the lifting core rod is required to be translated at the moment;
3. the lifting core rod has the problem of breaking down, and the lifting core rod has larger impact force when falling into a feeding roller of a core rod feeding end from a lifting hook, damages the surface of the core rod and reduces the service life of the core rod.
The three problems are relatively independent, but are actually related to each other and even cause and effect, namely, the problem 1 is solved, and the problem 3, namely, the problem of loading and unloading impact force, is generated when the lifting hook lifting and conveying speed is unilaterally increased.
Therefore, how to design a translational conveying device for a mandrel can effectively solve the above three problems, and is a technical problem to be solved by the person skilled in the art.
